And in any case, you would still be wrong (the following is from Dave Armstrong):
[St. Paul] is in the same priestly thought-world in another utterance of his:
Romans 15:15-17 But on some points I have written to you very boldly by way of reminder, because of the grace given me by God [16] to be a minister of Christ Jesus to the Gentiles in the priestly service of the gospel of God, so that the offering of the Gentiles may be acceptable, sanctified by the Holy Spirit. [17] In Christ Jesus, then, I have reason to be proud of my work for God.
“Offering”? Offering of what? “Priestly service”? The word for “priestly service” is hierourgeo: Strong’s word #2418. It is defined by Strong (my hardcover copy from Riverside Book and Bible House) as “to be a temple-worker, i.e., officiate as a priest (fig.): — minister.” The online version (linked above) has “to minister in the manner of a priest, minister in priestly service.” It also notes (from Thayer’s Greek-English Lexicon) historical etymological definitions of “to be busied with sacred things; to be perform sacred rites” (from Philo), and “used esp. of persons sacrificing” (from Josephus). Compare Baptist Greek scholar A. T. Robertson for the basic definition: “to work in sacred things, to minister as a priest.”
Marvin Vincent’s Word Studies in the New Testament states (for Rom 15:16):
Ministering (ierourgounta). Only here in the New Testament. Lit., ministering as a priest.
Offering up (prosfora). Lit., the bringing to, i.e., to the altar. Compare doeth service, John xvi. 2.
Gerhard Kittel’s Theological Dictionary of the New Testament (abridged one-volume edition, p. 354) defines it as “’to perform sacred or sacrificial ministry.’ In Josephus and Philo it always means “to offer sacrifice” and often has no object. (hierourgia means “sacrifice” and hierourgema the “act of sacrifice.”)”
A Catholic Commentary on Holy Scripture (London: Thomas Nelson & Sons Ltd., 1953, Dom Bernard Orchard, General Editor), provides further helpful analysis:
The essential point in every explanation is to realize that the sacrificial terms used here are metaphorical, and that therefore this verse cannot be quoted against the existence of a specially consecrated priesthood in the Church when Paul wrote . . . The difficulties lie in the analysis of the metaphors. . . . To bring the Gentile world as a worthy sacrifice to the altar of God is probably all that Paul meant to say. For the same idea cf. Is. 66:19 f.
The Eerdmans Bible Commentary (Protestant, p. 1044) concurs:
Paul describes his divine commission in terms of the priesthood: a minister (Gk. leitourgos; lit. a ‘priest’; cf. Heb. 8:2), in the priestly service (Gk. hierourgon) and offering (Gk. prosphora) are three sacerdotal terms.
Thus, Paul has called himself a priest — using two different terms. We get the word liturgy from litourgos (Strong’s word #3011; cf. 3008, 3009, and 3010). Strong’s online, for word #3008 (litourgeo) applies it to, among other things, “priests and Levites who were busied with the sacred rites in the tabernacle or the temple.” The author of Hebrews applies one of these terms to priests in the Old Covenant sense in Hebrews 9:21; 10:11 and to Jesus as high priest in 8:2.
Given the central motif in the New Testament of Jesus as the sacrificial lamb, it stands to reason that the Sacrifice of the Mass would be associated with the Eucharist, as the central rite of Christian worship.
St. Paul also casually assumes the continued existence of altars among Christians (1 Cor 10:14-21), and altars are mentioned in the New Testament in other places (apart from the many mentions of altars in heaven), as well:
Hebrews 13:9-12 Do not be led away by diverse and strange teachings; for it is well that the heart be strengthened by grace, not by foods, which have not benefited their adherents. [10] We have an altar from which those who serve the tent have no right to eat. [11] For the bodies of those animals whose blood is brought into the sanctuary by the high priest as a sacrifice for sin are burned outside the camp. [12] So Jesus also suffered outside the gate in order to sanctify the people through his own blood.
Therefore, if the cross is overthrown by an altar (as John Calvin argues in his Institutes: IV, 18:3: “the cross of Christ is overthrown the moment an altar is erected”), then the New Testament is against the cross. Far more plausible is a state of affairs whereby Calvin has grossly misunderstood New Testament teaching; otherwise, Christianity (all Christianity: not just Catholicism) and the Bible alike are a mess of abominations and contradictions.
The Sacrifice of the Mass is hearkening back and making present (by God’s power alone, not “magic”) one supreme, sublime sacrifice, as the Mass does. We agree that Jesus performed His sacrifice once, forever and also that the sacrifice is eternally present, because it was an act of God, Who is outside of time, as well as an act of man. That’s why Jesus appears even in heaven as a slain lamb.
Masses are not innumerable sacrifices, but one and the same, brought to us, transcending time (as God does). But there is indeed a NT motif (above all, in Paul) of our participating in His sacrifice, too, which is not dissimilar to the notion of the Mass:
Romans 8:17 and if children, then heirs, heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him.
2 Corinthians 1:5-7 For as we share abundantly in Christ’s sufferings, so through Christ we share abundantly in comfort too. [6] If we are afflicted, it is for your comfort and salvation; and if we are comforted, it is for your comfort, which you experience when you patiently endure the same sufferings that we suffer. [7] Our hope for you is unshaken; for we know that as you share in our sufferings, you will also share in our comfort.
2 Corinthians 4:10-11 always carrying in the body the death of Jesus, so that the life of Jesus may also be manifested in our bodies. [11] For while we live we are always being given up to death for Jesus’ sake, so that the life of Jesus may be manifested in our mortal flesh.
Galatians 2:20 I have been crucified with Christ; it is no longer I who live, but Christ who lives in me; and the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.
Galatians 6:17 Henceforth let no man trouble me; for I bear on my body the marks of Jesus.
Philippians 3:10 that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death,
Colossians 1:24 Now I rejoice in my sufferings for your sake, and in my flesh I complete what is lacking in Christ’s afflictions for the sake of his body, that is, the church,
2 Timothy 4:6 For I am already on the point of being sacrificed; the time of my departure has come.(cf. 2:10)
1 Peter 4:13 But rejoice in so far as you share Christ’s sufferings, that you may also rejoice and be glad when his glory is revealed.

The NT teaches the priesthood of the believer, who is to offer sacrifices of praise, thanksgiving and good deeds - which would include one’s earthly ministry.
None of us offered Jesus as a sacrificial lamb.
“27He has no need, like those high priests, to offer sacrifices daily, first for his own sins and then for those of the people, since he did this once for all when he offered up himself.” - Hebrews 7
“23Thus it was necessary for the copies of the heavenly things to be purified with these rites, but the heavenly things themselves with better sacrifices than these. 24For Christ has entered, not into holy places made with hands, which are copies of the true things, but into heaven itself, now to appear in the presence of God on our behalf. 25Nor was it to offer himself repeatedly, as the high priest enters the holy places every year with blood not his own, 26for then he would have had to suffer repeatedly since the foundation of the world. But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself. 27And just as it is appointed for man to die once, and after that comes judgment, 28so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him.” - Hebrews 9
No priest offers Jesus - he offered Himself, once for all. The elders didn’t offer a sacrifice for their people. The sacrifice was offered by Jesus, once for all.
We are ALL priests - I believe that is Catholic teaching as well. And no one comes between us and Jesus.
11And every priest stands daily at his service, offering repeatedly the same sacrifices, which can never take away sins. 12But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God, 13waiting from that time until his enemies should be made a footstool for his feet. 14For by a single offering he has perfected for all time those who are being sanctified.
15And the Holy Spirit also bears witness to us; for after saying,
16 “This is the covenant that I will make with them
after those days, declares the Lord:
I will put my laws on their hearts,
and write them on their minds,”
17then he adds,
“I will remember their sins and their lawless deeds no more.”
18Where there is forgiveness of these, there is no longer any offering for sin. — Hebrews 10
